Q, Merauke, 25 September 1904. Iris red, bare space round the eyes white, bill and feet dark steel-blue. 



Native name : Kai. 



A very small spécimen ; wing 260 mm. The white colour of the bare space round the 

 eyes is interesting.

Mr. LORENTZ did not note the colour of the bare skin round the eyes. The birds belong 

 not to the largest ones; the wings of the four females measure 300, 298, 285 and 297 mm., 

 those of the two not sexed spécimens 300 and 305 mm. The type-specimen of Psittacus 

 triton Temminck, a female collected by S. MûLLER on Aiduma Island near the Triton Bay, 

 measures 310 mm. and spécimens in the Leyden Muséum from Doré and the Karon District 

 hâve a length of wing of 325 mm., but from Sorong, there are spécimens, which measure 

 300 mm. and from Sélé, south of Sorong, a maie, that measures 295 mm. From Waigéu, Gébé, 

 Salawati and Misool there are very small examples in the collection of the Leyden Muséum, 

 with a length of wing of 260 mm., but from thèse localities there are also spécimens, which 

 are even'as large as spécimens from N. W. New Guinea, f. i. a maie from Waigéu measures 

 320 mm. This species varies considerably in size, but the variations are individually ; at the 

 same place we find large and small individuals. The bill is also subject to variation. It seems 

 however, that birds from the Aru Islands are constantly smaller and never attain a length 

 of wing of 300 mm. and therefore only the form of the Aru Islands must be separated under
